I have a project (http://sourceforge.net/projects/qdvi/)
where I'm porting kdvi to Windows. The thing is pretty well working in my
local tree (the committed stuff does *not*, so don't try it out!) but I
have one Automake stumbling block. Here's the (working) snippet of my
Makefile.am, which
1. Visits the kdelibs subdirectory where it compiles and links
$(CONFIG_COMPILER).
2. Generates prefs.{cpp,h} and kvsprefs.{cpp,h} from those .kcfg files
using this kdelibs/$(CONFIG_COMPILER).
3. Goes on to compile the .cpp files into .$(OBJEXT) ones.
As I say, the Makefile.am works, but it's very fragile because prefs
{cpp,h} and kvsprefs.{cpp,h} must be placed first in my list of sources,
so that they're compiled before anything else which #includes prefs.h or
kvsprefs.h. At least that's what I hope happens, but there's nothing to
guarantee it.
I've tried adding these files to BUILT_SOURCES and to qdvi_nodist_SOURCES
and I've tried to make qdvi_SOURCES dependent on kvsprefs.cpp, but all
that happens is that the build process attempts to build them on the way
*up* the tree, before it's got to kdelibs to compile $(CONFIG_COMPILER). I
want it to build them on the way *down* the tree, after it's visited the
kdelibs subdirectory.
Any ideas on how to do this properly?
(yes, I know I'm abusing my position a little ;-))
